I wondered why those clear peaks had vanished when I added quotes. Here's one that combines the search terms without the quotes. It shows several March/April & October/November peaks: http://www.google.com/insights/search/#q=r%20code%20for%2Br%20manual%2Br %20tutorial%2Br%20graph%2Csas%20code%20for%2Bsas%20manual%2Bsas%20tutori al%2Bsas%20graph%2Cspss%20code%20for%2Bspss%20manual%2Bspss%20tutorial%2 Bspss%20graph%2Cstata%20code%20for%2Bstata%20manual%2Bstata%20tutorial%2 Bstata%20graph%2Cs-plus%20code%20for%2Bs-plus%20manual%2Bs-plus%20tutori al%2Bs-plus%20graph&cmpt=q I've been trying to make sense of Google Scholar searches. I'm obviously missing something basic. Here are two searches on www.google.com: sas - gets 68M hits sas OR spss - gets 74.3M hits. A bigger number as "OR" would imply. But when I do the same searches on scholar.google.com, here's what I get: sas - gets 4.6M hits sas OR spss - gets 1.65M hits How on earth can an "OR" get you less??
